Another program I wrote which will set a redstone signal (on all sides) when you are logged on. This can be used to turn on and off your machinery so you don't have to do it manually. This program use dropbox as well.

It works by checking a specific file (online.txt) in your dropbox Public/CCPrograms folder. If the file contains the word "online" the signal will be set, otherwise it will be reset. The computer checks this every 10 minutes.

To actually write the value into the file a batch file is required to run on your own computer:

This batch file (call it FTB.bat for example) will write the online.txt file, start FTB and then wait for the user to press enter when finished playing. When that happens the online.txt file will be reset again. To make it work you have to fill in the path (twice) to your FTB_Launcher.exe on the third line (marked [path]).

From now on you have to start FTB via this batch file instead than the normal launcher.
